Nanopatterning equipment. Close-up of a silicon wafer (centre) being etched with a nanopatterning tool developed at the IBM Zurich Research Laboratory. A nano-sized heatable silicon tip, 100,000 times smaller than a sharpened pencil point, was used to etch a polymer (plastic) surface. A record-setting world's smallest magazine cover (11x14 micrometres) was created in April 2014, a Guinness World Record. This method is intended to prototype a new generation of technologies, from energy efficient transistors for computers to microscopic security tags to prevent the forgery of documents.
